This invention relates to improvements in street markers.

The primary object of this invention is the provision of an improvedstreet marker and mould for making and assembling the same; the improvedstreet marker being adaptable for placement in concrete curbing, walls,and the like, and comprising color contrasted letters and framing, ofceinentile tious material, assembled in a secure and novel relation. l

Other objects and advantages of this inn vention will 'be apparentduring the course of the following detailed description. l5 In `theaccompanying drawings,

Figure l is a perspective view showing the application of the improvedstreet marker lor main plate to cementitious curbing, at a streetintersection. v

Figure 2 is a vertical sectional view taken through the marker showingthe construction thereof. p

Figure 3 is a view of a mold, used for precasting letters adapted to beused in a street marker.

VFigure 4; is a transverse sectional view taken through the metal moldof Figure 3,

showing the cementitious pre-cast letter therein.

Figure 5 is a vertical sectional view taken through the mold of Figure3. i

Figure 6 is a fragmentary longitudinal sectional view taken through amold used to cast the cementitious frame, showing the means for holdingthe pre-cast letters formed asshown in Figures 3 to 5 inclusive, duringe the pouring in the mold of Figure 6, of the cementitious frame formingmaterial.

vFigure 7 is a fragmentary longitudinal Y 49 sectional view takenthrough a mold used to pre-cast a cementitious slab or frame, accordingto this invention, using pattern letters which are withdrawn from theprecast slab to leave pockets or recesses which are later filled withthe .contrasting cementitious material poured into the pockets of themold. f `Figure8 is the mold of Figure 7, showing the pattern letters inposition after the pourking of the slab cement.

Figure 9 is a view of the mold of Figure 7 with the slab cement in placeand the pattern letters withdrawn, leaving the pocket voids of theletters.

Figure 10 is a view of the mold of Figure 7,y with the slab framepockets filled with letter forming contrasting cementitious material.

In the drawings, the preferred and modiiied forms of the invention areillustrative of the thought that the structure ofthe improved markerlmay be made in various ways. However constructed, it is preferred thatthe improved marker, designated by A in Figure l of the drawings,comprise a plurality of letters B, permanently and immovably held withina preferably cementitious frame or slab C; the latter in turn beingpermanently and rigidly secured in a poclreted relation within apreferably cement wall or curb D.

The letters B are per se of novel forma tion. That is, the samegradually increase in thickness from the street casing edge thereof tothe base edge thereof. In other words, counterfacing walls of theletters, and exposed surfaces, slope in a tapered or di vergent relationfrom the outer street facing edge `to the base edge, in order that theletters at the base portions thereof are securely anchored againstdisplacement from the frame or slab C.

The frame or slab C has the outer face thereof paneled or recessed at15, over that portion upon which the letters B are exposed. That is tosay, the margins of the slab or frame C project beyond the plane 4of thespaced portion of the said slab on which the letters are exposed, as isclearly shown in Figure 2 of the drawings, and elsewhere, as willsubsequently appear in describing the manner of molding or` precastingthe slab. The slab C is pre-cast of cementitious material, although itmay be formed of any approved material, and the same is shaped to insurea permanent anchorage in the wall or curbing D. Its side surfaces andthe top and bottom surface are divergent from the outer face of the slabC towards the base thereof. In other words, the slab increases in lengthand width from the outer face towards the inner face, beingsubstantially in the forni of a trapezoid whose non-parallel sides aredi-.

vergent at equal angles from the face of the slab. The slab C is castinto the cementitious curbing or wall D andV permanently held therein. Y

rhere are several ways by which the iniproved marker may be assembled.In the first method of constructingthe marker, the letters B are precastfrom cemeiititious material, and then assembledin their definiterelation l within a mold wherein the cementitious material is poured toform the slab C. rlhe precast letters B may be made in conventionalmanner-,that is, by using a pattern letter made preferably fromlaluminum or the like, and

`from which a mold is made in sand, as is done in ordinary foundry work,andthe cementitious or other molten material then poured in the sand andtaken out when hardened and to be subsequently placed in the slabmaterial of the concrete marker. The material of the precast letters Bis preferably plaster of paris,vwhite cement, or any material whichcontrasts'in appearance and color with respect to the material of whichthe slab is formed.

ln the rpreferred manner of forming thev pre-cast letters B, the metalmold F of F igures 3, 4 and 5 is provided, which includes a base 20,preferably of aluminum or other metal, having certain portions 2larising from the upper surface 22 thereof to assist in the formation ofthe letter to be cast. The base 2O is preferably provided with dowelprojections 23 at opposite sides thereof, and adapted to lit intosuitable sockets provided inwardly from the under surface of detachablefifi side walls 24 and 25 forming the mold. The side walls 24 and 25 areof course of the same material asthe base 20,and the inside sur'- faces26 thereof are shaped to conform to the letter which is being cast.Detachable top and bottom walls-27'and 28, are provided, having suitabledowel extensions 29 for fitting into dowel sockets provided in the endsurfaces of the mold walls 24 and 25, as

` shown in Figure 4. vThe walls 27 and 28 are detachable from the base2O and from the side walls 24 and 25, and are held centered on the basewith respect to the side walls 24 and 25 by the dowel extensions 29. The.end walls 27 and 28 of the mold F may be held in yplace by a suitableclamp K. The cementitious material is then poured into the thusyassembled'mold F and leveled off at the top thereof in anyapprovedmanner, and the pre-cast letter is thus permitted to harden.rlhe particular mold shown in Figures 3 to 5 of the drawings willpre-cast the letter A, and it is to be noted from Figure 5 that theinside fac-v ing Walls ofthe mold converge downwardly, to taper thethicknessof the letter from the top of the moldwith a graduallydecreasing thickness to the bottom surface 22y of the mold. The insidesurfaces of the side walls 24 and 25 are likewise tapered.

rlhe mold L for casting the slab or frame C is of novel formation,including upstanding walls 85, and a bottom 36. rllhe inside lsurfaces37 of the walls 35 slope vinwardly anddownwardly inra convergingrelation.

The bottom 36 isprovided with an insideA marginal groove 39 peripherallysurroundiiigthe insideof the mold at the base of the wall surfaces 37,and thus providing' accentral raised portion 40 on the bottom of themold which forms the inset face ofthe precast slab or frame C, as shownat 15 in Figure 2 of the drawings. Themold L at oppo site side walls isprovided withupwardly extending lugs 4l to which the ends 42 of aVtransverse bar 44 are bolted at 45 in a'detach-v able relation. Thetransverse bar 44 extends across the top of the mold, andris providedwith screw threaded openings 46 therein for adjustably receivingclamping screws 48. Prior to the assemblage of the bar 44, in thisposition, the pre-cast letters B are positioned ing the slab C is of anyapproved nature,

contrasting in color with the color ofthe prevh cast letters B, for anobvious purpose. When in the mold the' exposed surfaces of the letters Band slab C represent' the back of the marker A. The slab C, as thusformed, has the marginal edges thereof sloping in a divergent relationfrointhe countersunk face.k thereof to the back surface of the slab,asis readily apparent from Figure 6.

. W'hen assembled in the ywall orfcurbing D, the marker A, which is nowentirely pre-cast, is supported in any suitable relation in the properposition which it will maintainfinthe curbing, andthe material of thewall yor curb'-y ing D, which is preferably cementitious, is thenpoured, and the outer face 49 of the curb is flush with the outersurface of the marginal ribV which extends about the face oftheVinailrer, so thatthe countersunk face portion vof the marker in whichthey letters appear, will set inwardly a proper distance from theV outerface'of the wall or curbing D, as a protection.V When thus assembled,the marker 'A has the letters B permanentlyy secured against liabilityofl ldetachment from the slab C, and the marker slab C is itselfperinanently dove-tailed or set into the material of the wall or curbingD, against liability of any detachment orv working loose.y Y

According to the other method offorlning lll() ilu lil@

the marker A, illust-rated in Figures 7 to l0 of the drawings, the slabC is first pre-cast with pockets therein for subsequently receiving thematerial of the letters B which is then poured into the pockets in theslab, and allowed to harden. Under these conditions pattern letters Mare used, having the saine shape and characteristics of the pre-castletters B above described, and they are properly positioned on thebottom 36 of the mold L, as shown in Figure 7V of the drawings, and theclamping screws 48 of the mold are then screwed or clampeddownwardlyupon the pat-tern letters M; the latter preferably being provided withscrew threaded sockets 49a therein to permit insertion of the screwthreaded shanlrs of the members 48, to prevent any transverse shift ofthe pattern letters M when the material of the slab is poured. When thepattern letters M are properly positioned and held in place theniateiial of the slab isA poured and leveled o5, and allowed to harden,as shown in Figure 8. rlhe pat-tern letters M may then be easilywithdrawn, as the same have been greased or otherwise rendered suitablefor withdrawal from the material of the slab C when it rhas hardened,and the pockets 5l are then left in the thus hardened slab C, whereinthe material to form the letters B is then poured,

, as shown at 52 in Figure 10 of the drawings,

' and allowed Yto harden.

The letters B on the slab C thus formed, as shown in Figures 7 to l() ofthe drawings, are of course of contrasting color, preferably of aceinentitious Vquirements imposed by various municipal art commissions.

f Various changes in the shape, size, and arrangement of parts, maybemade to the forms of invention shown, without departing from thespirit of the invention or the scope of the claims.
